SAFE AND VAULT.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed November l23, 1906. Serial No. 344,741.

To all whom 'it may concern:

Be it known that I, WILLIAM F. SOIIULTZ, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and ments in safes and vau ts, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein:

Fi ure 1 is a horizontal sectional view of a sa e-door, the invention being illustrated in connection therewith merely for sake of convenience; Fig.2 a front elevation of the same, a portion of the door being broken away and the tubes which contain the cylindrical members being shown in section; Fig. 3 an enlarged sectional view of a portion of one of the tubes, with one of the rotatable cylindrical members likewise appearing in section yand Fig. 4 a similar view of a slightly modified construction. 25 The main object of the invention is to provide a structure which is both burglar and fire proof, theconstructionbeing especially designed to resist the use ofA the electric arcand of drills.

' While the invention is shown as applied to a safe-door, it is to be understood that it is .ap licable to safes and vaults generally.

n the drawings, Figs. 1 to 3 inclusive, A

' denotes the outer member of the door (or other structure) referably formed of cast steel and provided with inwardly-extending side Walls B. C denotes the inner member of the door, preferably formed of Bessemer steel and secured to the iianges of the side Walls B. Mounted withinthe chamber thus formed and adjacent tothe front wall thereof, is a series of tubes D, which are of such length as to stop shortof theupper and lower side walls B. The tubes are entirel surrounded by a suitable hard, non-conc uctin fireproof cement E, which entirely ls the chamber formed by the walls and effectually insulates the various tubes from one another and the walls of the chamber.

As will be seen upon reference to Fig. 1 the tubes are 'arranged in two tiers, one behind the other, vthe tubes in each tier being separated, with the tubes of onetier staggered with reference to those of the other4 tier Mounted within each tube is a' series of relthe structure.

.I claim is:

atively short cylindrical members F, vsaid members by preferencebeing formed of laminated iron and steel, as indicated by a andb, Fig. 3. It will be noted upon reference to the drawings, that the cylinders are smaller in diameter than the interior diameter of the containing tube, so that the cylinders may be free lto rotate therein should a drill cut into the tube, whereby the drill-point would be deiiected and as a conse uence the drill be broken or prevented from further penetrating y The rounded surface of the tubes also renders the d rilling thereof eX- tremely diflicult, and in and of themselves lthey afford an excellent protection against drilling. Should they be pierced, however,

the rotatable members or cylinders contained y therein will eifectually prevent further penetration and cause the drill to be broken. The non-conducting cement and the insulation of the tubes from each other and the walls prevent ythe effective use of an electric arc in the destruction ofthe door or wall. Y

In Fig. 4 there is shown a slightly modified construction, wherein a series of balls G is shown, the balls resting one upon another in the tube and being free to rotate-'and clamp or bind a drill which may pass through the wall of the tube.

It is evident that members of other shapes may be placed in the tubes, or members of cylindrical form will referably be employed. Having thus descri ed my invention, what 1. In la structure of the class specified, the combination of a wall; a body of cement in rear thereof;y a series of tubes embedded in such cement; and a series of rotatable members mounted in each of said tubes.

2. ln a structure of the class specified, the combination of a wall; a body of cement in rear thereof; a series of tubes embedded in such cement said tubes being out of contact withthe Wall and each other; and a series of cylinders rotatably mounted in each of said tubes.

3. In a structure ofthe character specivarying forms in each tube, though the?.

fied, the combination of a wall; a body of cement in rearl thereof; a series of tubes embedded in said ce1nent,"the.tubesbeing insulated from each other and from the Wall; and a series .of members rotatably mounted in each of said tubes.`

4.111 astructure ofthe character specified, the combination of a Wall; a body of cement in rear thereof; a series of tubes embedded in said cement and insulated from each other and said Wall; and a series of cylinders formed of laminated metal mounted in each of said tubes.

5. In a4 structure of the character speci-A fied, the combination of a wall; a body of cement in rear thereof; a series of tubes embedded in such cement, said tubes being arranged in a plurality of rows, the tubes of the various rows being staggered said tubes being likewise insulated from each other and the wall; and. aeries of rotatable members mounted in each of said tubes.

6. In a structureof the character specified, the'combination of a Wall; a series of tubes mounted in rear of said Wall, said tubes being insulated from each other and sald wall; and a series of rotatable members mounted in each of said ltubes.

7. In a structure of the class specified, the combination of a Wall; a bod of cement in rear thereof; a series of tu es embedded therein said tubes bein insulated from each other and the Wall; an a rotatable member mounted in each of said tubes.

In testimony whereof I have signed my name to this specification in the presence of Witnesses.
